Answer: Humphrey Davy
Thomas Edison, the famous and productive American inventor, sports a performance wash list including the invention of all kinds of gadgets. What is interesting about the list, however, is that a significant number of things we dedicate ourselves to Edison were easily refined by him in some way ̵
Edison did not invent electrical lighting or even the bulb itself. However, he experimented a lot with filament and light bulb construction to help produce one of the first economically viable bulbs. He also played a major role in the early development of power grids and power distribution. However, the actual invention of the bulb is an accolade reserved for Sir Humphry Davy.
During the first decade of the 19th century, Humphry Davy gave the first demonstration of a bulb. The device, which we now refer to as an arc lamp, bends large amounts of electricity between two columns. The lighting was extremely light and impractical for residential applications. The original demonstration was more a demonstration of the concept than anything else, as the arc quickly drained the battery to which it was attached. With the advent of more advanced electrical delivery systems (such as power grids and power generators), the arc became more practical, albeit with limited applications. The lamps were used for large buildings and for public areas that needed light lighting.
Various experts attempted to tamper with Davy's brilliant arcs of light for something more practical for small-scale applications (like in a home or business), but with limited success. Early attempts to create longer lasting threads failed because eventually the filaments would burn up due to the acidic environment around them. During the 19th century, experiments were performed with different filaments, but it was not until inventors, who started with Warren de la Rue and Frederick de Moleyns, began to pump out the air and create vacuum chamber with incandescent lamps that the filaments stood a chance.
Edison raised his attention to the problem of electric lighting in the late 1800s, and after much experimentation and studies of failed earlier incandescent lamps, we began using strings of carbonated bamboo as a filament. His early incandescent lamps had a light life of about 1200 hours, which was enough to gain public attention and interest.
